The Dynatrac 0.25 inch collar spanner pin wrench (DT9191014) is a pin-style spanner for turning collars that are drilled for a pin.
Fitment
Dynatrac lists it as universal fit. The 0.25 inch size is part of the tool name, so check it against the holes or slots on the collar you plan to turn before ordering. Dynatrac's listing does not name a specific collar, shock or vehicle.
